Title: Welding of nodular cast iron - using electrodes contg. silicon carbide so welds free from martensite or ledeburite are obtd.
Inventor: KESSL WERNER
IPC: B23K35/365
Filed: 1980-05-05
Abstract: The welding operation is undertaken in the presence of silicon carbide, esp. by using a welding electrode which contains silicon carbide. Alternatively, the welding electrode is provided with a sheath contg. SiC. In conventional welding processes for nodular cast iron, hard structures of martensite and/or ledeburite may be formed in or near the weld, so the iron cannot be machined, and/or contains undesirable internal stress, so that post welding heat treatment is essential. The invention eliminates these problems. A welded zone can be obtd. in which the matrix consists only of ferrite and pearlite, i.e. the weld is ductile.

Title: Central heating circulation pump switching control - responds to water temp. at output of hot water boiler
Inventor: CLASEN-SCHULZ GEORG DIPL ING
IPC: F24D19/10
Filed: 1980-09-29
Abstract: The switching control for a central heating circulation pump uses a temp.-responsive switch positioned directly after the boiler. The switch causes the circulation pump to be switched on when the water delivered by the boiler is above the switching temp. setting of the room thermostat and causes it to be subsequently switched off when the boiler output is below this temp., the pump only being switched back on when the boiler is again fired. Several heating systems for different rooms may each have a temp. switch for controlling the switching of the circulation pump. The switches are connected in parallel. The switching control minimises the electrical energy used by the circulation pump.

Patent DE-3046538-A1 (DE)
Inventor: BLATTER JOHANN
IPC: H01H33/02
Filed: 1980-12-10
Abstract: In order to transmit relatively large forces in an economical manner between the ends of a drive rod tube (3) and a collar (4), these parts (3, 4) are connected by means of an asymmetric trapezoidal thread (30, 40). In this case, the thread base (BM) of the collar thread (40) is longer than the thread base (BR) of the tube thread (30), the ratio of the sizes preferably being 2:1. Furthermore preferred is a thread flank angle (A) of 60 DEG  and an overlap height (H) which amounts to approximately a quarter of the triangle height (HS) of a corresponding, symmetrical thread (7) with sharp pitches. The glass-fibre reinforcement of the plastic tube (3) should consist of a low-alkali glass which is free of boron and boron compounds, for example of a commercially-available R-glass as a result of which the thread (30) is provided with a particular resistance capability against decomposition products of SF6, which resistance can also be protected by filling the thread clearance (9) with two-component epoxy resin. <IMAGE>

Title: Multi-purpose element, in particular a filler for installations for exchanging energy and/or mass or for eliminating drops
Inventor: FAIGLE HEINZ
IPC: C02F3/10
Filed: 1981-03-20
Abstract: The multi-purpose element serves as a filler in installations for exchanging energy and/or mass or in eliminator plates or the like. Although in this case the aim is a compact design in the smallest possible space, exchange surfaces which are as large as possible are to permit a satisfactory mixing of the media without, however, it being possible because of the constricted and narrow ducts for the liquid flowing from top to bottom to run out sufficiently easily as a consequence of cohesion or adhesion only when by means of special design configurations of the duct ends cohesion and adhesion forces can be minimised thereby. The multi-purpose element consists in this case of helical surfaces, which are arranged next to one another and have essentially parallel axes, or of hollow bands bounded by such surfaces, the sense of rotation of adjacent helical surfaces being opposite. The result is to impose a circulating movement on the media flowing through the multi-purpose element, resulting in the achievement of long flow paths inside the multi-purpose element, on the one hand, while on the other hand as a consequence of the alternately opposite sense of rotation all the tangential flows of the media in the contact zones of adjacent spirals are rectified, so that low pressure losses occur nevertheless only inside the multi-purpose element. <IMAGE>

Title: Electro-erosive machining method and appliance
Inventor: INOUE KIYOSHI
IPC: B23H7/22
Filed: 1981-06-12
Abstract: A multiplicity of conductive tube elements is arranged parallel to one another, insulated from one another and is connected with one another to give a multiple-electrode arrangement. The electrode arrangement is fed into a workpiece in the erosion feed direction and, in addition, offset, in a plane perpendicular to the erosion feed direction, by a distance relative to the workpiece, which slightly exceeds the uniform spacing of the tube electrodes along two mutually perpendicular axes of the plane. The additional offset can be achieved by vibration of the tube elements transverse to their axes with an amplitude which is essentially equal to the spacing. For further machining of the same workpiece, a part of the tube elements can be released from its firmly clamped state and individually displaced in a forward and/or backwards direction with an extent and rate of movement which determines the course (profile) of the finished shape. The voltage supply has an AC-DC-HF-DC pulse inverter whose multiple outputs are each connected with the multiplicity of tube elements.
